+129845 The circumference of the Earth at the equator = 40,075.16 kilometers = about 40,075,160 m
The speed of light = 299,792,458 m / s
So .. Distance /Rate = Time ... 40,075,160 / 299,792,458 = about .134 seconds
The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.
